ABBOT AUGUSTUS LOW, OF BROOKLYN, NEW YORK.

HYDROCARBON-BURNER.

$PEGIFICAT1ON forming part of Letters Patent No. 684,073, dated October8, 1901.

Application filed November 26, 1900. Serial No. 37,709. (No model.)

To all whom it may concern: 7

Be it known that I, Annor Ancusrns Low, a citizen of the United States,residing in the city of New York,borough t Brooklymcounty of Kings, andState of New York, have invented certain new and useful Improvements inIIydrocarbon-Heaters, of which the following is a specificationsufficient to enable others skilled in the art to which the inventionappertains to make and use the same.

My improvements relate to what are known as hydrocarbon heaters ortorches, used for effecting a preliminary heating of theignition-chamber of gas-motors and for similar purposes where heat is tobe applied temporarilyand superficially.

My invention consists in the special construction and arrangement ofparts herein described and claimed specifically.

In the accompanying drawings, Figure I is an elevation of ahydrocarbon-heater of a form ordinarily used for the purpose designatedwith my improved attachment applied thereto. Fig. 2 is a section uponplane of line 2 2, Fig. 1. Fig. 3 isa central longitudinal section. Fig.4 is a horizontal section, partly in elevation, on plane of line 4 4,Fig. 1. Fig. 5 is a section upon plane of line 5 5, Fig. 1.

A is the cylindrical shell in which the ordinary vaporizing-tube B issituated, said tube being fed through the supply-tube b, in which isinterposed the usual needle-valve V, through which the vaporizedhydrocarbon escapes under pressure sufficient to drive the flame throughthe nozzle N in the end of the cylinder A.

O is a receptacle for holding an asbestos Wick or equivalent and forcontaining the alcohol to be used in the preliminary heating of thevaporizing-tube B. Attached to or combined with this lamp-chamber G is apipe P for supplying compressed air to the alcohol flame arising fromthe chamber 0. This air-pressure pipe 1? is provided with perforationsor nozzles 19, inclined in such relation to the chamber 0 and to thevaporizing-tube B as to cause the flame from the chamber 0 to impingeforcibly against the tube B, the compressed air at the same timeintensifying the heat of the flame; The compressed air supplied to thepipe P or its equivalent maybe derived from any convenient source, asfrom a tank '1, indicated symbolically in the drawings and connectedwith the pipe P by means of flexible tubing F. v In this connection itis obvious that a compression-p11 mp or other source of supply may besubstituted for the tank T with like result.

In the use of gas-motors having ignitionchambers which require to beheated externally before the motor can be made to run continuously theelement of time is of special importance under all conditions of use,and for this reason by rendering the hydrocarbon heater or torchinstantly available I effect a material and substantial advantage, Whileadding to the safety and convenience of the users of gas-motors of thisclass.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the cylindrical shell A, formed with thecontractingnozzle N, the supply-pipe b, the vaporizing-tube B, the needie-valve V, controlling the delivery of hydrocarbon from thesupply-pipe b, to the vaporizing-tube B, the lamp-wick chamber 0,secured to the lower rear edge of the shell A, and the air-pressure pipeP, formed with the series of perforations p, inclined toward thevaporizing-tube B, and arranged to direct the flamefrom chamber 0,against the vaporizingtube, the whole arranged and operatingsubstantially in the manner and for the purpose set forth.

ABBO'I AUGUSTUS LOW.
